L'Oréal Extraordinary Oil Serum is a hair care product formulated to smooth and nourish dry, frizzy hair. It contains a blend of six rare flower oils, including Lotus, Chamomile, Flax, Tiare, and Rose, which work together to impart a smooth, shiny appearance without weighing hair down. Versatile in use, it serves multiple purposes such as a pre-shampoo treatment, heat protection during styling, a styling serum to tame flyaways, and an overnight deep conditioning treatment for enhanced hair nourishment.
